A major source of teen stress is school exams，and test anxiety is not uncommon. When you recognize your teen is under stress，how can parents help your teen stay calm before an exam?

Be involved. Parents need to be involved in their teen’s work.  71 _ What they look for is your presence—to talk，to cry，or simply to sit with them quietly. Communicate openly with your teen. Encourage your teen to express her worries and fears，but don’ t let them focus on those fears.

Help them get organized.  72   Together，you and your teen can work out a schedule in which she can study for what she knows will be on the test.

Provide a calm environment. Help your teen set up a quiet place to study and protect his privacy(隐私). Give them a nutritious diet. It is important for your teen to eat a healthy，balanced diet during exam times to focus and do her best.   73    If this happens，encourage your teen to eat light meals or sandwiches. A healthy diet，rather than junk food，is best for reducing stress.

Help your teen balance her time so that she will feel comfortable taking time out from studying to spend time with friends or rest.

Show a positive attitude.   75  Your panic，anxiety and blame contribute to your teen’ s pressure. Make your teen feel accepted and valued for her efforts. Most importantly，reassure (安慰)your teen that things will be all right， no matter what the results are.
